How does encryption work to secure data?
Think of encryption as sending a secret message. Here is how it goes: Creating the Secret Code: Suppose you and your friend have this very special code book which shows you how to make up ordinary words into secret code.

Think of encryption as sending a secret message. Here is how it goes:
Creating the Secret Code: Suppose you and your friend have this very special code book which shows you how to make up ordinary words into secret code. In the digital world, this codebook is called an “encryption key.”
Locking Up the Message: You use the encryption key to mix up your message (e.g., email or file) before you send it. To someone without the key, this jumbled message appears like some meaningless set of characters.
Sending the Secret Message: You send the scrambled message over the internet. It will not be understood by anyone who intercepts because it is in secret language.
Unlocking the Message: After receiving the mixed-up message, your friend uses their version of an encryption key that changes scrambled message into its initial state. This process is commonly referred to as “decryption.”
So, encrypting is more like putting your information inside a locked box. Only with appropriate keys can one open and read it. As a result, unauthorized individuals are denied access to personal data.
